Fast Water, Rivers & Lakes


Oil Containment Systems

Oil spill response operations are notably difficult in rivers with strong current. In addition, when considering response times for river spills in relation to the mobilisation time required for conventional land- or vessel-based boom systems, a timely response is often a logistic impossibility especially in the more remote regions. Therefore, equipment must be readily at hand near the sites of operation and pre-rigged lines, cables and mooring areas are a must. Selection of a good location to deploy the oil containment system is dependent upon prior planning and understanding of the currents. Drift studies, river run off histories, tidal current tables and charts, plus computer modeling are all useful tools to understand the flow patterns and to develop recovery strategies. Reading the currents and flow patterns require practice and understanding of the hydrodynamics involved. Several things may be helpful to define these patterns. Selection of a containment area where a lower current exists is desirable and this will allow wider deflection angles and reduce drag forces on the boom.

Natural collection sites should be identified and listed in the relevant contingency plans as part of the planning process to select control points for spill response operations. This can be effectively accomplished by surveying and then conducting an investigation of suitable sites by land or water. Viable control points should have favorable currents, helpful circulation patterns and logistic support such as roads, wide-open banks, and sufficient water depth for fully loaded vessel and good mooring selections. These sites also collect oiled debris that will complicate the collection and removal process.

An accurate determination of current direction and velocity is important in order to select the proper tactic and deploy the equipment correctly. Wind loads are not significant in high-current areas but the loads created by wind-induced currents can affect the equipment performance so the effect of the wind must be considered. Once the current is known, the angle for boom deployment can be determined. Oil losses can be minimized if the angle is set at a maximum angle.

In the above regard, DESMI have many years of experience and in addition have a boom with proven oil spill response that has exceeded all other booms in the difficult fast water and river environments. DESMI can boast that the GlobeBoom has outperformed all other product in its class.
